CONNECTING MULTIPLE MOTU FIREWIRE
INTERFACES
You can daisy-chain up to three MOTU FireWire
interfaces on a single FireWire bus, with the
restrictions described in the following sections.
Most computers have only one built-in FireWire
bus (even if it supplies multiple FireWire sockets).
Connect them as follows:
Figure 4-21: Connecting multiple 896mk3’s (or other MOTU FireWire
audio interfaces) to a computer.
Multiple interfaces cannot be bus-powered
Do not run the Traveler, UltraLite or other bus-
powered interfaces under bus power when
connecting them with other devices on the same
FireWire bus.
Multiple interfaces in MOTU Audio Console
MOTU Audio Console displays the settings for one
interface at a time. To view the settings for an
interface, click its tab as shown below in
Figure 4-22.

Synchronizing multiple interfaces
When multiple MOTU interfaces are connected,
choose a Master Clock Source from the menu in the
General tab (Figure 4-23). You can choose any
available sync source from any connected interface
(as shown in Figure 4-23), giving you a great deal
of flexibility in choosing a clock source.
A separate Clock menu is provided for any
interfaces not chosen as the master clock source, as
demonstrated with the 896mk3 Hybrid in
Figure 4-23. You can either resolve the interface to
the Master Clock Source or to one of its own digital
inputs or other sync sources. The latter scenario is
useful for externally resolving the interface with the
the interface chosen as the Master Clock Source.
